BERNHARD SCHROEB, OF HAMBURG, GERMANY.

WICKET.

To all whom it may concern Be it known that I, BERNHARD SoHRonR, asubject of the German Emperor, residing at Hamburg, Germany, haveinvented a new and useful Vicket, of which the following is aspecification.

The devices hitherto used upon the entrance or outer doors of apartmentsand the like which have observing holes (with or without glass windows)or doors with vsecurity chains or the known observing mirrors which aremounted before the doo-rs or windows, allow only the observation of alittle part of the field of the view. Furthermore the known observingholes in doors which can be closed by covers or doors have only a verylittle field of view. The object of the invention is an improvedsecurity device for observing through the outer entrance doors ofapartments and the like.

In the drawing two forms of construction of the device are represented.

Figure 1 shows a perspective view of the one form having an opened door.Fig. 2 is a vertical section, Fig. 3 represents a perspective view ofthe back part of the device seen from the place of the observer. Fig. 4shows a horizontal section through the device and a part of the entrancedoor. Fig. 5 represents a perspective view of the second form ofconstruction and Figs. 6 and 7 are vertical sections on an enlargedscale in opened and closed position.

The observing device consists of a casing g which is arranged behind aslit in the door. In the slit of the door is mounted a frame or casingfor the mirrors whose front is closed by a glass plate c'. For securingthe mirrors a door f is pivoted to the outer side of the slit in theapartment door. The door is opened by a spring m and can be closed bymeans of a pulling cord f1 by the observer' behind the apartment door.The door f can be provided with sign boards and can be made oit' metalporcelain wood or the like. Furthermore the door f can be made with aseparate door for a letter boX. The sidemirrors o, Z are obliquelyarranged against the inner side of the apartment or entrance door. Theside mirrors o, CZ are rigidly connected with the horizontal mirrors eand b and the glass plate i; thereby forming a rigid frame or casing.

Specification of Letters Patent.

Application filed December 29, 1913.

Patented June 23, 1914.

Serial No. 809,373.

Since the form of the mirrors has greater dimensions at the inner sideof the apartmentdoor the removing of the mirrors is only possible in thedirection of the inner side of the apartment door and thereby the casingg of metal secures the frame or casing of mirrors in the oblique slit inthe apartment door. The frame of the outer door f can be affixed to thecasing g by means of pins or screw bolts.

The second form of construction seen in Figs. 5J? shows side mirrors o1Z1 which are mounted upon doors which are drawn toward the inner side ofthe apartment door by means of springs. By the opening of the door f theside mirrors c1, Z1 are pressed rearward by arms f2 which are aiiixed tothe clap-door f. When the door f is lifted and has arrived at thehorizontal position, the side mirrors c1, l1 are no longer arrested bythe arms f2 and the spring causes them to move sidewise and then thedoor f covers all 7 the slit room and the mirrors therein. F urthermorethe inner side of the door f can be provided with a mirror f3.

The operation and motion of the mirrors c1, d1, f3 are the same as inthe other form of construction by a chain or cord f1. The back wallconsists of a wall g1 with a slit for observing.

I claim:

l. An observing security device for entrance doors consisting of a frameor casing formed by obliquely arranged mirrors (c, d, b) a door (f)pivoted to the front side of said frame or mirrors and means for openingor closing said door in the inward o-r outward direction by theobserver.

2. Observing security device for entrance doo-rs comprising incombination: a frame, formed by obliquely arranged mirrors (o, d, b), adoor (f) pivoted upon said frame and means for moving said door in theinward or outward direction and means for moving the singular particularside mirrors (c1, (Z1) in outward direction if the door (f) is outwardlymoved.
